Ceiling-recessed, motorized projection screen with independently motorized masking system installed in the same case for dual format projection.Flat black mask on second motor-in-roller converts the projection screen to a 4:3 NTSC format by masking the right and left sides of the viewing surface.Height of viewing surface remains constant.Both projection screen and masking system are independently controlled, each using any standard or optional control. Two, SS-1Rs are supplied. Or, select AMV-C, a low voltage control that allows both motors to be controlled by independent 3-button switches in a single box.Depending on surface, available in sizes through 133" diagonal HDTV format or 136" diagonal WideScreen format.U. S. Patents 6,137,629; 6,421,175; 6,532,109; 6,816,308 and other patents pending. Custom sizes available.

Textile Backed Screen Surfaces
In this group, the reflective surface is laminated to a woven textile base. The screen surface hangs suitably flat because of the stability of the material and the weight of the bottom dowel. Good for all types of projection. Commonly used for single lens video projection, as well as for CRT video and data-graphics projection.

Screen Surfaces

Matt White
A matt white surface diffuses projected light in all directions, so image can be seen from any angle. Provides accurate color rendition as well as superior clarity. Recommended for use with all high light output projection devices. Requires control of ambient light in the audience area. Washable, flame and mildew resistant. Seamless in virtually all standard sizes.

High Contrast Grey
Grey, textile-backed surface offers excellent resolution while enhancing the blacks of LCD and DLP projected images, even as whites and lighter colors are maintained. Performs well in ambient light. Lower gain of 0.8 allows use with even the brightest projectors. Available on most non-tensioned motorized and manual screens, seamless in sizes through 8' high. Viewing cone of 180°.

Gain: .8

Viewing Cone: 120 Degree Viewing Cone

AT1200
The most innovative and versatile acoustically transparent screen material. Similar in gain performance to Matt White and does not require tensioning for flatness. Acoustical properties comparable to the finest speaker grille cloth. Washable, flame and mildew resistant. Available in sizes through 72" x 96" or 10' diagonal. Not recommended for screens smaller than 80" wide when used with LCD or DLP projectors.

Gain: 1.0

Viewing Cone: 180 Degree Cone

AT Grey
Offers the acoustical properties of our popular AT1200, while providing the best optical qualities of both Matt White and High Contrast Grey. It is unique in that it offers both a 180° viewing cone and the vivid color contrast associated with high contrast grey materials. Washable, flame and mildew resistant. Gain of 0.8. Available in sizes through 72" x 96" or 10' diagonal. Not recommended for screens smaller than 80" wide when used with LCD or DLP projectors.
